A case control study reveals that polyomaviruria is significantly associated with interstitial cystitis and vesical ulceration

Abstract

Objectives: To investigate whether polyomaviruses contribute to interstitial cystitis pathogenesis. Subjects and Methods: A prospective study was performed with 50 interstitial cystitis cases compared with 50 agematched, disease-free controls for the frequency of polyomaviruria. Associations between polyomaviruria and disease characteristics were analysed in cases. Polyomavirus in urine and bladder tissue was detected with species (JC virus vs. BK virus) specific, real-time PCR. Results: Case patients were reflective of interstitial cystitis epidemiology with age range from 26-88 years (median 58) and female predominance (41/50 F). There was a significant increase in the frequency of polyoma..
